Definitions
- the invention relates to a vessel and more particularly to a pressure vessel and a method for forming the vessel, wherein the vessel includes a hollow liner formed from an extruded film tube and a pair of end caps.
- a Type I vessel is a metal vessel.
- a Type II vessel is also a metal vessel, the vessel having an outer composite shell disposed on a cylindrical section thereof.
- a Type III vessel consists of a liner produced from a metal such as steel and aluminum, for example, and an outer composite shell that encompasses the liner and militates against damage thereto.
- a Type IV vessel is substantially similar to the Type III vessel, wherein the liner is produced from a plastic.
- the liner is manufactured using conventional forming processes such as a welding process, a rotational molding process, and other similar processes, for example.
- a welding process multiple components of the liner are welded together at seams of the components.
- the weld seams may not be fluid-tight and permit permeation of the stored fluid from the vessel. Further, the welding process limits the types of material which can be used to form the liner.
- the rotational molding process is slower and produces a liner having an adverse thickness.
- the liner is formed by disposing bosses in a die cavity with a polymer resin, heating the mold while being rotated to cause the resin to melt and coat walls of the die cavity, cooling the die, and removing the molded liner.
- the bosses may not properly adhere to the liner resulting in formation of a space therebetween. If the bosses are not properly adhered to the liner, a fluid-tight seal between the bosses and the liner may not form. Without a fluid-tight seal, the contents of the vessel may escape therefrom to the atmosphere.
- adhesives, heat welding, and other similar processes may be employed.
- an adapter device as disclosed in U.S. Pat. No. 7,032,767, hereby incorporated herein by reference in its entirety, may also be used to ensure a fluid-tight seal. Such processes and additional devices may be time consuming and require manual process steps, thereby resulting in an increased cost to produce the vessel.
- a vessel and a method for producing the vessel including a hollow liner and at least one boss, wherein an efficiency of the method is optimized and a cost thereof is minimized, has surprisingly been discovered.
- a method of forming a vessel comprises the steps of: forming a hollow liner including a first end cap and a second end cap, wherein the first end cap includes a first boss and the second end cap includes a second boss; and forming an outer shell over at least a portion of the hollow liner and at least a portion of the bosses.
- a method of forming a vessel comprises the steps of: forming a first end cap of a hollow liner including an interfacial layer and a first boss; forming a main body of the hollow liner; disposing the first end cap on the main body of the hollow liner; and forming an outer shell over the main body and at least a portion of the first end cap of the hollow liner.
- a vessel comprises: a first end cap including an interfacial layer and a first boss; a thin main body abutting at least a portion of the first end cap; and an outer shell formed around at least a portion of the first end cap and the main body.
- FIG. 1 is a cross-sectional elevational view of a vessel according to an embodiment of the invention
- FIG. 2 is a cross-sectional elevational view of a vessel according to another embodiment of the invention.

Abstract
Description
- The invention relates to a vessel and more particularly to a pressure vessel and a method for forming the vessel, wherein the vessel includes a hollow liner formed from an extruded film tube and a pair of end caps.
- Presently, there are a variety of vessels designed to contain various fluids such as compressed natural gas (CNG), hydrogen gas for use in a fuel cell, and the like, for example. A common technique for storing the fluid is in a lightweight, high pressure vessel resistant to punctures. Traditionally, such vessels are divided into four types. A Type I vessel is a metal vessel. A Type II vessel is also a metal vessel, the vessel having an outer composite shell disposed on a cylindrical section thereof. A Type III vessel consists of a liner produced from a metal such as steel and aluminum, for example, and an outer composite shell that encompasses the liner and militates against damage thereto. A Type IV vessel is substantially similar to the Type III vessel, wherein the liner is produced from a plastic.
- Typically, the liner is manufactured using conventional forming processes such as a welding process, a rotational molding process, and other similar processes, for example. During the welding process, multiple components of the liner are welded together at seams of the components. The weld seams, however, may not be fluid-tight and permit permeation of the stored fluid from the vessel. Further, the welding process limits the types of material which can be used to form the liner. On the other hand, the rotational molding process is slower and produces a liner having an adverse thickness. During the rotational molding process, the liner is formed by disposing bosses in a die cavity with a polymer resin, heating the mold while being rotated to cause the resin to melt and coat walls of the die cavity, cooling the die, and removing the molded liner. The bosses, however, may not properly adhere to the liner resulting in formation of a space therebetween. If the bosses are not properly adhered to the liner, a fluid-tight seal between the bosses and the liner may not form. Without a fluid-tight seal, the contents of the vessel may escape therefrom to the atmosphere. To ensure fluid-tight seals between the bosses and the liner, adhesives, heat welding, and other similar processes may be employed. Alternatively, an adapter device as disclosed in U.S. Pat. No. 7,032,767, hereby incorporated herein by reference in its entirety, may also be used to ensure a fluid-tight seal. Such processes and additional devices may be time consuming and require manual process steps, thereby resulting in an increased cost to produce the vessel.
- It would be desirable to develop a vessel and a method for producing the vessel including a thin hollow liner and at least one boss, wherein an efficiency of the method is optimized and a cost thereof is minimized.
- In accordance and congruent with the present invention, a vessel and a method for producing the vessel including a hollow liner and at least one boss, wherein an efficiency of the method is optimized and a cost thereof is minimized, has surprisingly been discovered.
- In one embodiment, a method of forming a vessel, the method comprises the steps of: forming a hollow liner including a first end cap and a second end cap, wherein the first end cap includes a first boss and the second end cap includes a second boss; and forming an outer shell over at least a portion of the hollow liner and at least a portion of the bosses.
- In another embodiment, a method of forming a vessel, the method comprises the steps of: forming a first end cap of a hollow liner including an interfacial layer and a first boss; forming a main body of the hollow liner; disposing the first end cap on the main body of the hollow liner; and forming an outer shell over the main body and at least a portion of the first end cap of the hollow liner.
- In another embodiment, a vessel comprises: a first end cap including an interfacial layer and a first boss; a thin main body abutting at least a portion of the first end cap; and an outer shell formed around at least a portion of the first end cap and the main body.
- The above, as well as other advantages of the present invention, will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment when considered in the light of the accompanying drawings in which:
-
FIG. 1 is a cross-sectional elevational view of a vessel according to an embodiment of the invention; -

In respect of the methods disclosed, the steps presented are exemplary in nature, and thus, the order of the steps is not necessary or critical.

Asecond gasket 26 such as a polymeric o-ring, for example, is disposed between thefirst component 21 and thesecond component 24 of the first dividedboss 20 to form a substantially fluid-tight seal therebetween. Thesecond component 24 receives a fluid-communication element (not shown) in a central aperture formed therein for communicating with aninterior 27 of thevessel 10 such as a valve, a fitting, a hose, a nozzle, a conduit, and the like, for example. It is understood that thesecond gasket 26 may be disposed elsewhere between thefirst component 21 and thesecond component 24, if desired.

Afourth gasket 38 such as a polymeric o-ring, for example, is disposed between thefirst component 32 and thesecond component 36 of the second dividedboss 30 to form a substantially fluid-tight seal therebetween. Thesecond component 36 receives a fluid-communication element (not shown) in a central aperture formed therein for communicating with an interior 27 of thevessel 10 such as a valve, a fitting, a hose, a nozzle, a conduit, and the like, for example. It is understood that thefourth gasket 38 may be disposed elsewhere between thefirst component 32 and thesecond component 36, if desired. Thegaskets first component 32 and thesecond component 36 of the second dividedboss 30 are separately produced finishes that form an opening into the interior 27 of thevessel 10, and are typically shaped to receive a closure element (not shown).

Thecomponents boss 30 may be formed of a metal or another conventional material having desired properties. - in the embodiment shown, the
outer shell 16 of thevessel 10 substantially abuts at least a portion of the second surface of theliner 12. A portion of theouter shell 16 is disposed on thesecond component 24 of the first dividedboss 20 and thesecond component 36 of the second dividedboss 30.

It is understood that theouter shell 16 can be formed by other methods as desired. - To form the
vessel 10, the thinmain body 13 of theliner 12 is formed by a co-extrusion blow film molding process. After themain body 13 of theliner 12 has been formed, thefirst end cap 14 and thesecond end cap 15 of theliner 12 are disposed on opposing ends thereof. Thefirst end cap 14 and thesecond end cap 15 are formed by any conventional forming process such as an injection molding process, a thermoforming process, and the like, for example. Theouter shell 16 is then formed around themain body 13 and at least a portion of the end caps 14, 15 using the filament winding and curing process. Once theouter shell 16 is cured, thevessel 10 is complete. - Alternatively, the
liner 12 is formed by a thermoplastic foiling and sealing process. During the thermoplastic foiling and sealing process, a thin foil sheet is formed by a thermoplastic foiling process. It is understood that the thin foil sheet can be a single layer, flexible, foil sheet or a multi-layer, flexible, foil sheet as desired. It is further understood that an additional coating process may be employed to apply to the thin foil sheet a material to militate against a permeation of the pressurized fluid therethrough such as a hydrogen barrier material, for example. The end caps 14, 15 are then disposed on opposing ends of the thin foil sheet. The thin foil sheet is wound around thefirst end cap 14 and thesecond end cap 15. A seem formed at contacting edges of the foil sheet is then sealed to form themain body 13. Thereafter, seems formed at contacting surfaces of themain body 13 and therespective end caps liner 12.

Asecond gasket 132 such as a polymeric o-ring, for example, may be disposed adjacent anannular shoulder 134 of theinterfacial layer 29′ and aninner surface 136 of theboss 130. Thegasket 132 is adapted to form a fluid-tight seal between theinterfacial layer 29′ and the fluid-communication element. It is understood that thegasket 132 may be disposed elsewhere between theinterfacial layer 29′ and the fluid-communication element, if desired. Thegasket 132 may be any conventional gasket formed from a material which facilitates forming a fluid-tight seal between two contacting surfaces. Theboss 130 is typically a separately produced finish that forms an opening into the interior 27′ of thevessel 10′, and is shaped to receive a closure element (not shown). Thevessel 10′ may include any number of bosses, as desired. Theboss 130 may be formed from any suitable material having desired properties such as a metal, for example. - In the embodiment shown, the
outer shell 16′ of thevessel 10′ substantially abuts at least a portion of theliner 12′. A portion of theouter shell 16′ is disposed on theboss 120 and theboss 130. Theouter shell 16′ is typically formed by a filament winding and curing process. When theouter shell 16′ is formed by the filament winding and curing process, theouter shell 16′ may be formed from a carbon fiber, a glass fiber, a composite fiber, and a fiber having a resin coating, for example. It is understood that theouter shell 16′ can be formed by other methods as desired. - To form the
vessel 10′, the thinmain body 13′ of theliner 12′ is formed by a co-extrusion blow film molding process. After themain body 13′ of theliner 12′ has been formed, thefirst end cap 14′ and thesecond end cap 15′ of theliner 12′ are disposed on opposing ends thereof. Thefirst end cap 14′ and thesecond end cap 15′ are formed by any conventional forming process such as an injection molding process, a thermoforming process, and the like, for example. Theouter shell 16′ is then formed around themain body 13′ and at least a portion of the end caps 14′, 15′ using the filament winding and curing process. Once theouter shell 16′ is cured, thevessel 10′ is complete. - Alternatively, the
liner 12′ is formed by a thermoplastic foiling and sealing process. During the thermoplastic foiling and sealing process, a thin foil sheet is formed by a thermoplastic foiling process. It is understood that the thin foil sheet can be a single layer, flexible, foil sheet or a multi-layer, flexible, foil sheet as desired. It is further understood that an additional coating process may be employed to apply to the thin foil sheet a material to militate against a permeation of the pressurized fluid therethrough such as a hydrogen barrier material, for example. The end caps 14′, 15′ are then disposed on opposing ends of the thin foil sheet. The thin foil sheet is wound around thefirst end cap 14′ and thesecond end cap 15′. A seem formed at contacting edges of the foil sheet is then sealed to form themain body 13′. Thereafter, seems formed at contacting surfaces of themain body 13′ and therespective end caps 14′, 15′ are sealed to form theliner 12′. It is understood that the seems can be sealed by any suitable method as desired such as by a welding process, a heat-sealing process, and the like, for example. Thefirst end cap 14′ and thesecond end cap 15′ are formed by any conventional forming process such as an injection molding process, a thermoforming process, and the like, for example. -
